The IXTK40P50P is a P-channel enhancement mode MOSFET designed for high-side switching and high-power applications, housed in a TO-264 package measuring 26.16 mm by 20.83 mm. It has a maximum drain-source voltage of -500 V, continuous drain current of -40 A at 25°C, and a maximum drain-source on-state resistance of 230 mΩ at -10 V gate bias. The device is avalanche rated, with a single-pulse avalanche energy of 3.5 J, and features a fast intrinsic diode and low package inductance. Its thermal resistance from junction to case is 0.14°C/W. It meets the AEC-Q200 qualification standard and supports operating junction temperatures from -55°C to 150°C. The part is suitable for applications including dc choppers, push-pull amplifiers, and automatic test equipment.
Polar™ P-Channel MOSFETS are fabricated using our Polar technology platform, which significantly reduces the on-state resistance (RDSon) by 30% and gate charge (Qg) by 40% in comparison to legacy counterparts, resulting in lower conduction loss and providing excellent switching performance. They are dynamic dv/dt and avalanche rated making them extremely rugged in demanding operating environments and can easily be paralleled due to an on-state resistance with positive temperature coefficient. These MOSFETs are ideal in a variety of applications, with best-in-class performance and competitive pricing. Applications include push-pull amplifiers, buck converters, DC choppers, power solid state relays, CMOS high power amplifiers, high current regulators, and high side switching in automotive and test equipment. The superior ruggedness of the Polar P-Channel Power MOSFETs also makes them suitable devices for motor control and power cut-off switches or power SSRs for energy saving applications. Advantages: Low gate charge results in simple drive requirement High power density Easy to parallel Fast switching Fast intrinsic diode Rugged PolarP™ process Avalanche rated Low package inductance Dynamic dv/dt rated
